Application filed June 23,

To all whom it may concern:

Be it known that I, FRANCIS B. CONVERSE, a citizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented a certain new and useful Tire-Building Machine, of which the following is a specification.

This invention relates to machines for building the carcasses of pneumatic tire caslugs, and its object is to orovide an improved mode of mounting the tools which work upon the sides of the casing, and especially those for working around the beads.

Of the accompanying drawings,

Figure 1 is a side elevation showing a portion of a tire-building machine provided with my improvements.

Fig, 2 is an end elevation thereof, omitting the core.

In the drawings, 10 is the ring core or mandrel supported upon the usual powerdriven chuck 11 and adapted to rotate in. a vertical plane. Fig. 1 shows a tire carcass 12 on the core. 1 is a base mounted on the floor 14, and 15 is a frame or standard slidingly mounted in guides on said base and adapted to be adjusted horizontally toward and from the core by means of a screw 16. The standard 15 carries at its upper end a fixed, transverse shaft 1? whose two ends constitute arbors or pivot shafts on which are slidingly and rotatably mounted a pair of triangular tool carriers 18, 18, each of which has mounted thereon a set of fabricworking tools for operating upon and around the tire beads. These tools may be of any suitable character, there being here shown three rollers 19, 20, 21 of difi'erent kinds for pressing and smoothin the tire fabric above and below the beads, and a knife 22 for trimming the edges of the fabric, The rollers are mounted on swivels 23 2%, 25, which are suitably constructed and mounted to furnish the necessary adjustments, and the knife is rovided with the usual toothed or threaded stem and ad justing nut 26.

To support the tool carriers in their elerated operative positions, there is provided a pair of adjustable stop screws 27, one of which is shown in Fig. 1, mounted upon the standard 15 and contacting with an abutment 28 on the tool carrier. Other stops 29 mounted on a cross-bar 30 on the standard arrest or' support the tool carriers in their depending inoperative positions. For swing- Speeification of Letters a is, 1919,

ing. the tool carriers from one position to the other they are provided with laterally' pro ectlng handles 31 at their upper corners.

For sliding the tool carriers axially or 66' pivoted at 36 to the standard 15, the horizontal arm of said'lever being pivoted at 37 to a vertical link 38 Whose lower end 'is. pivoted at 39 to the short arm of a treadle lever 40 or 41, fulcrumed on the standard at 42. nected with a stud 4e on. an upper extension of the link, and its lower end connected with a fixed stud 55 on the standard, the springs tending to depress the links and move the tool carriers axially inward.

The tool carrier 18 at the front in Fig. 1 v is shown in its elevated 'operative position, and the one the left in Fig. 2 in correspondingly elevated, while the other has been depressed to an inoperative position by 9 swinging it downwardly, and inwardly toward the vertical axial plane of the core. The core being omitted in Fig. 2, the hub of the left-hand carrier is shown abutting against the standard. In its operative posi- 5' tion, it is somewhat retracted to the left, and the spring 13 yieldingly holds said carrier with Til-S rollers laterally against the tire' The right-hand carrier in this View is shown partially retracted by the depression of the treadle +11. The extreme outward sliding of the carrier clears the tools from the tire core, and also enables the abutment 28 to clear the upper ston 27., The carrier is manually raised or lowered by grasping the into its normal plane, whereupon it is 10% allowed to rest on either of the stops .27 or 29.

Heretofore, swinging and sliding toolcarriers of the type here shown have been placed substantially level with the middle horizontal plane of the ring-core, and mounted to swing upward and'backward from their operative positions. My improved arrangement involves less muscular effort on the part ,1 the attendants in shift- 11o ing the toolcarriers, requires less travel on their part in walking around the machine,
